Description

a stroller for children

technical field

The utility model relates to a stroller for children.

Background technique

At present, the operating mechanism between the tooth block and the push handle seat of the children's stroller is usually a button, which is slidably arranged on the push handle seat or the push handle along the sliding direction of the tooth block. The tooth blocks on both sides of the push handle seat slide, so the buttons on both sides will be inconvenient to operate.

Contents of the invention

The purpose of the utility model is to provide a stroller for children, in which the first slide block is operated to realize the locking and unlocking between the tooth blocks on both sides and the push handle seat.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a children's stroller, including a frame, a seat arranged on the frame, a front wheel assembly arranged under the front part of the frame, and a The rear wheel assembly below the rear part of the frame, the frame is provided with a push rod, the upper end of the push rod is provided with a push handle seat, and the push handle seat passes through the first rotating shaft A push handle is connected, the rotation axis of the first rotating shaft extends along the left and right directions of both sides of the cart, and the push handle seat wraps around the first The rotating shaft is provided with a plurality of first tooth grooves extending axially along the first rotating shaft, the distance from the first rotating shaft to the bottom surface of each of the first tooth grooves is equal, and the plurality of The first tooth slots are arranged at equal intervals in turn, and the push handle is provided with a plurality of first rotation shafts extending axially along the first rotation shaft on an end portion opposite to the first tooth slots. Two tooth grooves, the distance from the first rotation axis to the bottom surface of each of the second tooth grooves is equal, a plurality of the second tooth grooves are arranged at equal intervals in sequence, and the first tooth grooves There is a tooth block slidingly arranged in the inner or the second tooth groove along the left and right sides of the trailer, and a tooth block is provided between the tooth block and the push handle to provide a return of the tooth block. The elastic part of the force, the tooth block has a locked position that prohibits the rotation of the push handle relative to the push rod and an unlocked position that allows the rotation of the push handle relative to the push rod. When the tooth When the block is in the locked position, the tooth block is located in the first tooth slot and the second tooth slot at the same time; when the tooth block is in the unlocked position, the tooth block is located in the In the second tooth groove, an operating mechanism for switching the tooth block between the locked state and the unlocked state is provided between the tooth block and the push handle seat. The first passage on the push handle seat, the first slide block that is at least partly slidably arranged in the first passage, the second passage opened on the left and right sides of the push handle seat, along the left and right sides of the cart The second slider is slidably arranged in the second channel and is used to resist the movement of the tooth block, the sliding direction of the first slider intersects the sliding direction of the second slider, and the The first slider is on the side opposite to the second slider, and the second slider is on the side opposite to the first slider. At least one of the two parts has a guide The operating mechanism has a first operating state in which the tooth block is in a locked state and a second operating state in which the tooth block is in an unlocked state. When the operating mechanism moves from the first operating state to the second When the operating state is changed, the first slider is in conflict with one side of the second slider, and the other side of the second slider is in conflict with the tooth block.

The first sliding block is provided with a first sliding hole along the direction where the first sliding block slides, and the first rotating shaft slides through the first sliding hole.

The second sliding block defines a second sliding hole along the sliding direction of the second sliding block, and the first rotating shaft slides through the second sliding hole.

A pressing cover is arranged on the first slider, and one end of the pressing cover is rotatably connected with the push handle seat through a second rotating shaft.

The sliding direction of the first slider extends along the front and back direction of the cart.

Because the utility model has adopted above technical scheme, its advantage is:

The locking and unlocking between the tooth block of the stroller and the push handle seat is realized by the sliding of the first slider in the first channel. When the tooth block is converted from the locked position to the unlocked position, the first slider is pulled, The first slider pushes the second slider, and the second slider pushes the tooth block. The tooth block is located in the push handle to realize unlocking, otherwise it is locked. Operating the first slider can easily realize the tooth block and push handle on both sides. Locking and unlocking between seats.
